    \since QtLocation 5.0

    \brief The ImageModel element provides a model of place images.

    The ImageModel is a read-only model used to fetch images related to a \l Place.  The model
    performs fetches incrementally.  The number of images which are fetched at a time is specified
    by the \l batchSize property.  The total number of images available can be accessed via the
    \l totalCount property.

    The model returns data for the following roles:

    \table
        \header
            \o Role
            \o Type
            \o Description
        \row
            \o url
            \o url
            \o The URL of the image.
        \row
            \o imageId
            \o string
            \o The id of the image.
        \row
            \o mimeType
            \o string
            \o The MIME type of the image.
        \row
            \o supplier
            \o \l Supplier
            \o The supplier of the editorial.
        \row
            \o user
            \o \l {QtLocation5::User}{User}
            \o The user who contributed the editorial.
        \row
            \o attribution
            \o string
            \o Attribution text which must be displayed when displaying the editorial.
